ICOP Technology is embracing and expanding into Projected Capacitive Touch (PCAP) technology by implementing it as an option for our line of 9-inch touch panel devices.
Despite being introduced to consumer level technologies over a decade ago, it’s taken some time for PCAP to enter the industrial sector of production and manufacturing. This can be attributed to the conditions in which these panels would be operated in as PCAP operates under the principle of sensing electrodes on a touch panel and a conductive object rendering operation with gloves difficult or impossible. Here is a quick diagram of how PCAP works:

However, as more things become increasingly automated and operation of machinery becomes more complex, the option of a PCAP solution is a welcome addition to the standard Resistive Touch Panels.
For a list of differences between Resistive and Projected Capacitive Touch, please see the table below:
| Description | Resistive | Projected Capacitive |
|---|---|---|
| Cost | Low Cost | Additional Cost for Features |
| Scratch Resistance | Subject to Scratches | High |
| Detection Precision | Low | High |
| EMI Immunity | Good | Based on Cost |
| Touch Point | Single | Multi |
| Chemical Cleaning | Non-Chemical Cleaning | Chemical Cleaning Approved |
| Application | Single Touch Application | Multi-Touch Applications |
Different projects and applications have different requirements and ICOP is happy to announce that we will be supporting both touch panel options for the foreseeable future. Some applications that are utilizing PCAP currently include: medical, consumer electronics, kiosks, etc.
Projects and applications that are optimized and perform better with Resistive Touch are: healthcare, automation, and food production due to the possibility of lower cost and needing to wear gloves or hand protection.
